Guess you can toss that avatar....wouldn't want your kid to go to therapy over that!!
Congrats. Having kids is very scary and being scared can be a good thing and it's much better than being indifferent.
What I would say to anyone becoming a parent is:
Be a part of the pregnancy.
Let your kid be a kid, in all phases of his or her childhood.
Be the parent, but let your long-lost child emerge to once again see the world through your offspring's eyes.
Don't lose your humanity. Humans make mistakes and every parent makes them. But when we don't admit them and don't allow our kids to see us as human beings, we lose their respect.
Relax and go with your gut.
